“…The buried object spectrum at ky ko = 3 shown in figure 9 has gone undetected. The convolution process to construct the auxiliary source that was described in this paper can be thought of as a form of structured light illumination or wavefront engineering [73][74][75][76][77][78][79][80]. Along these lines, for example, a plasmonic lens imaging system was discussed recently in [73], where the authors described the fields on the image plane by Eq.…”

We present an active physical implementation of the recently introduced plasmon injection loss compensation scheme for Pendry's non-ideal negative index flat lens in the presence of realistic material losses and signal-dependent noise. In this active implementation, we propose to use a physically convolved external auxiliary source for signal amplification and suppression of the noise in the imaging system. In comparison with the previous passive implementations of the plasmon injection scheme for sub-diffraction limited imaging, where an inverse filter post-processing is used, the active implementation proposed here allows for deeper subwavelength imaging far beyond the passive post-processing scheme by extending the loss compensation to even higher spatial frequencies.Although this form of passive inverse filter provides compensation for absorption losses, it is also prone to noise amplification [56]. This is illustrated in figure 1 which shows an object with three Gaussian features separated by λ o /4, where λ o is the free space wavelength. Noise is prominent in the Fourier spectra beyond ky ko = 2.5 as seen in figure 2. However, the compensated image is still reasonably well resolved. Consider now the object shown in figure 3, which has four Gaussians separated by λ o /4. The Fourier spectra of the raw image, shown in figure 4, demonstrates how the feature at

“…Two-dimensional plasmonic photonic crystals (2D-PCCs), which can localize and enhance the electromagnetic fields and hence control the propagation of light, have attracted a lot of attention recently due to their widespread applications in photonics, such as planar optical components, nonlinear optics, super-resolution imaging, optical trapping, chemical and biological sensing, and so forth. These applications require advanced, sophisticated, and scale-up fabrication techniques with a flexibility to control many material and structure parameters of 2D-PCCs.…”

Shadow sphere lithography (SSL) is a powerful and large-scale fabrication method to produce two-dimensional (2D) plasmonic photonic crystals and three-dimensional metamaterials. Practically, one of the biggest challenges for SSL-based fabrications is that it is hard to accurately predict the physical properties of the fabricated nanostructures if the structures were only modeled by the geometric shadowing effect. A Monte Carlo (MC) simulation is developed to show that the dynamic shadowing effect due to the accumulation of materials on the template as well as the thin-film growth mechanism plays a key role in determining the structure details. For a one-to-three step-based SSL fabrication, the nanostructures predicted by MC match very well with those produced experimentally, and the plasmonic properties predicted by these MC-simulated structures are also consistent with the features obtained experimentally, both qualitative and semi-quantitative. This study indicates a possible solution to use MC simulation and numerical calculation to guide the design of the plasmonic photonic crystals and metamaterials based on SSL for optic applications.

“…However, the spatial frequency of the structured illumination pattern is restricted by the propagating dispersion of SP in this method, and is comparatively low. To increase the spatial frequency of the structured illumination pattern, metal-insulator-metal plasmonic waveguide structure is reported, the sub 80 nm imaging resolution was reached, however, the super-resolution imaging is achieved only one in-plane orientation [24]. To further improve the resolution, localized surface plasmon SIM imaging technology (LPSIM) is reported [25][26][27][28].…”

Because structured illumination microscopy (SIM) has the advantages of wide-field, rapid imaging, and biocompatibility, it is widely used for super-resolution imaging of living cells. Here, we demonstrate a new super-resolution imaging method—bulk plasmon polariton based SIM (BPPSIM), which combines the SIM with the hyperbolic metamaterials (HMMs). By utilizing an HMM composed of a multilayer metal/dielectric film, a deep subwavelength bulk plasmon polariton is obtained. The imaging resolution of BPPSIM can be improved by the uniform and wide-field structured illumination pattern with high spatial frequency, benefiting from the filtering effect of HMM for the spatial frequency spectrum. The resolution of the recovered images by BPPSIM has been increased to 1/8 of the fluorescence wavelength, which is 2.7-fold enhancement in resolution compared with traditional fluorescence microscopy. This proposed approach demonstrates the operability and flexibility of the structured illumination pattern and can be used in a simple, wide-field and super-resolution fluorescence microscope.
